        Overview Manuals Specifications Application Communication Safety and Compliance

        Features:

        • Provides seamless, bumpless switchover between primary and backup controllers with real-time memory, I/O, and logic state synchronization; zero data loss during transitions
        • TÜV-certified for IEC 61508 SIL3 safety integrity level; suitable for Emergency Shutdown (ESD), Fire & Gas (F&G), and Burner Management Systems (BMS)
        • Supports online replacement without system shutdown; built-in advanced diagnostics monitor module health, communication status, and fault conditions for proactive maintenance
        The FC-TCNT11 is engineered for high-availability safety systems where controller failure cannot be tolerated. It enables dual redundant configurations where a primary and backup controller operate in synchrony. The module continuously monitors the health of both controllers and manages automatic failover. When the primary controller fails, the backup takes over instantaneously (bumpless switchover) without any interruption to the safety logic execution. Real-time synchronization ensures that memory contents, I/O states, and logic execution are perfectly aligned between the two controllers at all times.

        The FC-TCNT11 is TÜV-certified for IEC 61508 Safety Integrity Level 3 (SIL3), the highest rating for industrial safety systems. This certification confirms that the module meets stringent requirements for systematic capability, architectural constraints, and random failure mitigation. Safety Instrumented Systems (SIS) built with FC-TCNT11 modules can claim SIL3 capability for entire safety loops. Typical applications include Emergency Shutdown (ESD) systems that isolate hazardous processes, Fire & Gas (F&G) detection systems that trigger alarms and suppression, and Burner Management Systems (BMS) that control boiler startups and shutdowns.

        The FC-TCNT11 is designed for maintainability in 24/7 operations. Its hot-swappable construction allows a technician to remove and replace a module without powering down the system or interrupting safety functions. This is crucial in continuous processes where shutdowns are prohibitively expensive (e.g., ethylene crackers, LNG plants). The module also features comprehensive onboard diagnostics: status LEDs indicate power, communication activity, network health, and fault conditions. Advanced diagnostics continuously verify critical functions including memory integrity, communication link status, and internal voltage rails.

        The FC-TCNT11 Honeywell Controller Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

        Description
        The FC-TCNT11 (part number 51307928-176) is a redundant IOTA (Input/Output Terminal Assembly) controller module engineered for Honeywell’s SC S300 Safety Manager and Experion PKS platforms. It serves as a critical communication bridge between redundant controllers and field I/O modules in Safety Instrumented Systems (SIS). 

        When using the FC-TCNT11, engineers benefit from automatic, seamless failover between primary and backup controllers. The module maintains real-time memory, I/O, and logic state alignment across dual communication paths, ensuring zero data loss during redundancy transitions. Hot-swappable design allows replacement without system shutdown, significantly reducing maintenance downtime in critical processes. 

        The FC-TCNT11 operates on 24V DC power and is designed for harsh industrial environments with an operating temperature range of -20°C to +70°C. For legacy Honeywell safety system expansions or repairs, the FC-TCNT11 provides a robust redundant controller solution. It seamlessly integrates with Honeywell Experion PKS and Safety Builder platforms.

        Technical notes
        The FC-TCNT11 is a redundant IOTA (Input/Output Terminal Assembly) controller module, not a standalone processor. It works in conjunction with SC S300 processor modules to provide fault-tolerant controller redundancy for safety applications.The module features dual communication paths with automatic failover.
